MIKKUPPA M12x1.5 ATV Lug Nuts for Polaris & Aftermarket Wheels — 19mm Hex, Triple Chrome

MIKKUPPA M12x1.5 ATV lug nuts are closed-end, bulge-seat replacement fasteners engineered to fit many Polaris and aftermarket ATV wheels.

These lug nuts combine an M12x1.5 thread, 60° conical seat and a 19mm hex profile with triple chrome finish and heat-treated steel construction. They are built to match common Polaris wheel studs while resisting corrosion and thread wear, intended for owners replacing lost, damaged or mismatched hardware on UTVs and ATVs.

How do these lug nuts fit my Polaris or aftermarket wheels?

MIKKUPPA lug nuts use the M12x1.5 metric thread and a 60° conical (bulge) seat that aligns with many Polaris wheel designs and common aftermarket rims. The 19mm hex size and 1.4-inch length provide clearance for most wheel surfaces while ensuring secure engagement with studs.

• M12x1.5 thread pitch — standard for listed Polaris models
• 60° conical seat — intended to match hub seat geometry
• 19mm hex — fits standard 19mm sockets and hand wrenches
• 1.4 in. length and 0.87 in. width — balanced for clearance and grip

What materials and finishes protect these lug nuts from rust and wear?

The nuts are cold-forged from heat-treated steel and plated with a triple-chrome finish to improve corrosion resistance and surface hardness. Precision machining of threads reduces cross-threading risk and helps maintain a reliable fit under vibration and load.

• Cold-forged, heat-treated steel — higher tensile strength
• Triple chrome plating — enhanced rust resistance and appearance
• Closed-end design — blocks dirt and moisture from entering the threads
• Precision-cut threads — smoother engagement with studs

How should I install and torque these lug nuts for safe use?

MIKKUPPA recommends hand tightening with a hand wrench and avoiding electric impact tools for final installation to prevent over-torquing or thread damage. Use a calibrated torque wrench to set the manufacturer's recommended torque for your vehicle, then recheck after initial use.

• Initial fit by hand or hand wrench to avoid cross-threading
• Avoid impact wrenches for final seating to protect threads and finish
• Use vehicle manufacturer torque specs and a torque wrench
• Re-torque after first 50–100 miles of operation

Which Polaris models and aftermarket wheels are these lug nuts compatible with?

These lug nuts fit a range of Polaris UTVs and many aftermarket wheels that accept M12x1.5 metric nuts with a 60° conical seat. They are listed as compatible with popular Pioneer, Ranger, RZR and General variants produced in the model years indicated by Polaris.

Who is this for? These MIKKUPPA lug nuts are aimed at ATV and UTV owners, mechanics and wheel shops who need reliable replacement hardware for Polaris and compatible aftermarket wheels. If you want durable, corrosion-resistant lug nuts with a common metric thread size and a closed-end bulge seat for cleaner threads and consistent fit, this set is appropriate. For proper safety, always verify thread pitch and seat style on your vehicle and follow factory torque specifications during installation.
